SKEIN-DYEING MACHINE;

Specification of Letters Patent. Patented J an. 13, 1.920'.y

Application led August 22, 1917. Serial No. 187,531.

To all whom t may concern: f

Be it known that I, `HOWARD M. DUDLEY, a citizen of the United States,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inSkein-Dyeing Machines, of which the following is a specification.

My invention relates to skein dyeing machines and refers particularly tomachines suitable for the dyeing o-skeins by means of a circulating dyeliquor.V

One object of my invention is a device whereby skeins of textile fibersmay be dyedY evenly without manual manipulation.

Another object of my invention is a device in which a dye liquor may bepassed lin opposite directions through fiber skeins.

Another obj ect of my invention is a device in which those portions ofthe skein which rest upon the supporting bars are dyed evenly with otherportions of the skein.

Another object of my invention is a device in which the dye liquor isdistributed evenly throughout the dyeing chambers.

Another object of my invention is a device in which the skeins may bewashed and oxidized after dyeing, the oxidation being accomplished bymeans of an oxidizing solution or by means of air or a suitable gas.

Another object of my vinvention is a testing device whereby thecondition of the fiber in the dyeing chamber may be determined withoutopening the dyeing l,chamber or disturbing or injuring the skein yarnstherein. These and other objects of my invention will be evident upon aconsideration of my specification, drawings and claims.

In the dyeing of skein yarns it is necessary that the skeins be movedcontinuously through the dye liquor or that the dye liquor be passedcontinuously through the skeins in order that all portions of the yarnreceive equal treatment to produce even dyein s.

It isl further necessary in the dyeing of fibers of this character, tosuspend or support each skein separately in order that the fibers maynot become tangled and thus in-v terfere with the further operations.There is a tendency toward uneven dyeings at those portions of the skeinwhich rest upon these supportingmeans, and which are usually notsubjected to the same treatment as those portions which arey subjectedtofree treatment of thel dye liquor.

My device overcomes all of the above and other diiliculties and presentsa method whereby 4uniform and even dyeing results may be obtained with aminimum of time, labor andexpense."

In the drawings forming'a part of this specification, and in whichseveral forms of the device of my inventionr aref'illustrated, similarparts are designated'by'similarnumerals. i'

The particular form of the device of my invention .illustrated in thedrawings, comprises a dyeing chamber formed by the side members 10 and11, the end members 12anrdv 18, the top 14 and thebottom 15.v The endconstruction of the topy 14; is shown in Fig. k7 and comprises aAdownwardly extended end member 16,' the upper extendedmember 17 havinga series oi'gholes through which the wing nuts 18, 18 may be .insertedtothread"V with threaded'holes in the flange 19 'of the end members 12 and13 and the side .members l() and 11 of the dyeingchamber, the wing nutsvthus serving to fasten lthe top 'llt'upon f the side andv end members ofthe ldyeing chamber the lowerl portion of the member. :16 abuts upon theinner surface'of the sidesy and ends of.. the dyeing chamber, thusformingay tight joint. A kchamber 2O extends along, the end between themember 16 and the-up#` wardlyiexte'nded portion-,21 of the end 'inember13 and a similar'chamber 22 is formed along the upper portion of theother end of the dyeing chamber.

A series of foraminous pipes 23, 23 extends across and within the topmember 14 and open into the chamber 20, the pipes 23, 23 passing throughthe holes 24, 24 in the members 16, 16 of the top 14 as shown in Fig. 7.A series of pipes 25, 25 connect the chamber 2() with the pipe 26,having the valve 27, the pipe 26 being connected with the pipe 28, whichis in turn connected with the delivery chamber of the pump.y 29.

The bottom 15 contains a series of foraminous pipes 30, 30 extendingwithin and across the bottom member and opening into the chamber 32. Aseries of pipes 33, 33 connect the chamber' 32 with ythe pipe 34 havingthe valve 35; the pipe 34 is connected with the pipe 28.V

A series of openings 80, 80 connects the interior of the top 14 with thechamber 22 and a similar series of openings 81, 81 connects the interiorof the bottom 15 with the l chamber 31.

A testing device whereby the condition of the liber in the dyeingchamber may be determined `without .opening the dyeing chamber orinterrupting the operation therein, is shown in detail in Fig. 5. Amember 36 containing the conduit 37 and having the valve 38, connectsthe chamber 31 with the lower end of the fiber chamber 39, the upper endof the liber chamber being connected to the chamber 22 by means of themember 40 containing the conduit 41 and having the valve 82. The fiberchamber 39 has the upper and lower extended flanges 42 and 43, themember having the extended flange 44 capable of abutment upon the flange42 and the member 36 has a similar flange abutable upon the lowerflange43 of the fiber chamber 39. rIhe iber chamber is retained in theposition shown in lFig. 5 by means of the collar clamp members 45 45,hinged at 46 46 and capable of being clamped by means of the two wingbolts 47 47. IVithin the fiber chamber 39 is a yarn skein supportingframe. 48, having a series of rods 49, 49 upon which the yarn skeins 50,50 may be retained.

Within the dyeing chamber there is a removable yarn supportframe 51,carrying a series of upper and lower rods 52, 52 upon which the yarnskeins 53, 53 may be retained. The support may be removed from thedyeing chamber by means of the chain 54. The supporting frame 51 restsupon the angle members 55, 55 which are integral with the sides 10 and11 of the dyeing chamber.

The foraminous pipes 23, 23 30, 30 have a series of interruptedlongitudinal openings 56, 56 positioned inwardly toward the dyeingchamber.

pipe l5"? having the valve 58, connects the upper portion of thedyeingchamber with the top of the reserve tank 59.

A ipe 60, having the valve 61 is connected with the pipe 57. i

The bottom of the reserve tank 59 is connected with the pipe 62 havingthe valve 63, the pipe 62 being connected to the receiving chamber ofthe pump 29.

The pipe 64, having the valve 65, connects the pump 29 with a dissolvingtank not shown. Y

The pipe 66 having the valve 67 connects the pump 29 with a source ofwater supply.

The pipe 68 having the valve 69 is connected with a source of airsupply.

In the modification of the oraminous pipes shown in Figs. 10 and 11, theopenings 70, 7 0 are transverse of the pipe.

The operation of' the device is as follows y VThe yarn support 51 isloaded with the yarn skeins 53, 53, care being takenthat the skeins donot bind between the'upper and lower rods 52, 52, and then placed withinthe dyeing chamber. The top 14 is' then placed upon the device andclamped thereto. The testing device is similarly charged with the skeins50, 50 and placed imposition. All of the valves are then closed-with theexception of valves 65, 35, 38, 82 and 58, and the pump 29 started.Thedye liquor from the dissolving tank, not shown, passes through thepipe 64, the pump 29, the pipe 28, pipes 33, 33 the chamber 32, theoraminous pipes 30, 30, the dyeing chamber, and the pipe 57 into thereserve tank 59.

When suflicient dye liquor has been introduced, valve is closed andvalve 63 is opened, thus allowing a continuous circulation of the liquidthrough the dyeing machine, the reserve tank and the pump. From time totime valves 38 and 82 are closed and the testing device 39 removed, theyarn 50 examined and the testing device replaced. r1`he flow of theliquid through the device is reversed by closing all of the valves withthe exception of valves 63, 27, 82, 38 and 61. In this case the liquoris forced by the pump 29 through the pipe 28, pipe 26, pipes 25, 25,chamber 20, top 14, oraminous pipes 23, 23, the dyeing chamber and pipe60 into the reserve tank 59, at the same time the liquid passesdownwardly through the testin device 39. It is to be noted that if the sreins 53, 53 are not'held tightly by the bars 52, 52, the skeins will befloated away from the bars, and thus, that portion of the skeins whichnormally rests upon the bars will be dyed. When the dyeing operation iscompleted, all of the valves are closed with the exception'of valve 100,thus drawing the liquor from the dyeing chamber.

In order to wash the skeins without removing them from the dyeingchamber, all of the valves are closed with the exception of valves 67,35, 38, 82, and 58, fresh water thus passing through the pipe 66 intothe pump 29 and fromV thence being forced through the dyeing chamber inthe same manner as the dye liquor was forced. Vhen the goods aresuiiiciently washed, all of the valves are closed with the exception ofvalves 69, 35, 38, 82 and 58 and air forced through the pipe 68 and fromthence through the dyeing chamber in the same manner as the liquid waspreviously forced. In this manner the skeins are dried or oXidized asdesired. After these., operations are completed, the top 14 is removedand the frame 51 carrying the skeins 53, 53 is withdrawn by means of thechain 54.

I do not limit myself to the. particular size, number, form orarrangement of parts as shown and described, all of which may be variedwithout going beyond the scope of my invention as described and claimed.

What I claim is l. In a fiber treating device, in combination, a dyeingchamber, a removable frame adapted to carry fiber skeins within thedyeing chamber, a series of foraminous pipes below the frame, meanswhereby a liquid may be removed from the dyeing chamber above the frame,a removable top carrying a series of foraminous pipes, means whereby aliquid may be removed from the dyeing chamber.
